I don't understand why you would want to face a difficult boss at such a low level. My advice would be to possibly level up some more, get better weapons and armor, and then face that boss. I would help but i see no reason to keep a character that low, sorry.

Its really for the challenge, they're the last bosses I've got left before the kiln.

I've got other characters on NG++ and just wanted to try out something a bit differnet - it means that you have a few self inflicted restrictions (eg you can't just level up your health, stamina, equip load and take any high end weapon to beat them) although I have to admit I'm tempted to go up to SL8 to use the scythe and magic barrier.

I am getting closer to beating them though so it's definitely making my skills better

Well, I'm pretty well buffed - ring of favour and protection, fully upgraded sealers dress and top (as good as Smoughs armour vs magic), mask of father (extra HP) and a +10 fire hand axe... havent got the stats for any magic blocking spell.

I'm gonna try my +9 Estoc and Crest (80% magic) shield (I heard dark hand blocks their attacks well too) and try turtling it... as blocking their attacks is quite effective, its just when they get me while I'm swinging, maybe combined with magic shield spell, I just wish the witch would pull her weight!

Thanks for the offer caffinated, I finally beat them last night, seems by not taking the witch in with me the later spawning kings didn't get angered so they stopped double teaming me plus I went full-on with the Great fireball and fire orbs, which killed them off surprisingly quickly - and no Kaathe's not there...
